JOHN CHAPMAN AND ROBERT'BRASS, OF BROOKLYN, NEW YORK.

STEAM-RADIATOR.

SPECIFICATION forming part of LettersPatent No. 258,374, dated May 23,1882. Application lcd December 17, 1881. (No model.)

To all whom it may concern:

Be it known that we, JOHN CHAPMAN and ROBERT BRASS, citizens of theUnited States, residing at Brooklyn, in the county ot' Kings and Stateof New York, have invented certain new and useful Improvements inSteam-Radiators; and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

Our invention relates to certain new and useful improvements insteam-radiators. It has for its objects to effect a more perfectcirculation ofthe steam with consequent greater radiation, andthefurther object of the perfect discharge of air and products ofcondensation, so as to prevent the annoyance ot' the usual thumping orhammering noise. l

Our inventionalso has for its objects to simplit'y the details ofconstruction, as will b'e hereinafter set forth. t

Our invention consists in the particular construction and arrangementot' parts hereinafter described and specifically claimed.

In the drawings, Figure l is a central vertical section of asteam-radiator embracing the features of our invention. Fig. 2 is atransverse section taken on the line .r rv, Fig. 1. Fig. 3 is a top viewwith the cap of the upper receptacle removed. Fig. 4 is a Vtop view withthe cap in place, and Fig. 5 is an end view of the upper receptacle.

Similar letters indicate like parts iu the sev eral figures.

a is a steatntight inlet-pipe connected to the upper steamreceptacle, b,within which is ar,- ranged centrally a horizontal steam-conduit pipe,c, provided with a series ot' exit-holes along its bottom, as clearlyshown at Fig. l.

f are the vertical pipes connecting the upper receptacle, b, andthelower receptacle, g. These pipes are screwed into the top of thelower receptacle, g, and are provided at their upper ends with nipplesd, which are secured thereto by a screw-thread. The upper ends of thenipples pass through the bottom plate of the upper steam-receptacle, b,and are secured thereto by screw-nuts d. The nipples d have a centralvertical orifice, t', for the passage of the steam from the receptacle binto the pipes f, and thence to thelower receptacle,.g. 4A suitableWasher is used, either between the shoulder of the nipple d and theunder side of the bottom plate of the receptacle b or between the nut dand said plate, to make a steam-tight joint. The nipples d and `nuts dnecessarily project above the bottom plate of the receptacle b, and anyproducts ofcondensation existing in said cylinder are thereforeprevented from entering any ofthe tubesf except those two at theendnearest to the exit h in the 'bottom receptacle, g, and designated byletter f and in order that the produetsof condensation shall enter andbe discharged through such two end pipes we form in one end ot' thereceptacle b a downward projection to form a transverse trough, e, sothat `the nipples and nuts connecting the two pipesfat such point shalllie within or below the plane of the bottom of the remainderofthereceptacle b, whereby all waters from condensation gravitate to thetrough c and nd their escape through the pipes at such point, and outofthe exit-pipe h in the end ot' the lower receptacle, g, the bottom ofwhich, to facilitate such exit, iuclines, as clearly-seen in Fig. 1, tosaid exit h. The top receptacle is made in two parts, and they aresecured together by screw-bolts and nuts, as clearly shown at Figs. etand 5.

From the construction shown and described it will be seen that the steamenters .at ct into` the pipe c, escaping into the ltop receptacle, b,which is heated by the radiated heat from pipe c, and also by directheat of the escaping steam. All condensation gravitates through theopenings in the bottom of pipe c down onto the bottom plate ofthereceptacle into the trough e, and thence through the two end pipes intothe bottom receptacle, and is discharged at h, while the dry steamcirculates through the balance ot' the pipes f betweenthe upper andlower steam-receptacles, bg.

What we claim as new, and desire to secure by Letters Patent, is-

l. The top receptacle, b, and lower receptacle, g, connected bycirculating-pipesf, secured within the bottom plate ofthe upperreceptacle by nipples d, attached to the'ends of the pipes byscrew-threads, said nipples passing loosely through the bottom plate ofthe receptacle verse trough, e, below the bottom ofthe recepand securedin place by nuts d', whereby the tacle to receive the products ofcondensa-tion, joiutmay bepacked,substuutiully asdescribcd. incombination with the end pipes,f, and nip- 2.
